Aim:
To separate a solution from a precipitate ( a precipitate is a solid that forms a liquid ).
Equipment:
- filter paper
- funnel
- 200ml beaker
- stirring rod
- lead nitrate
- conical flask
Method:
1. Pour approximately 10ml of copper sulfate solution into a beaker.
2. Add the same volume of lead II nitrate and potassium iodite solution. A precipitation reaction will occur, resulting in a cloudy blue precipitate of copper carbonate.
3. Your teacher will show you how to fold the filter paper so it fits inside your funnel.
4. Place the funnel, with the filter paper inside it, into the mouth of a conical flask.
5. Carefully pour the precipitate mixture into the funnel.

Observations: Outline what you saw happen:
We mixed the lead II nitrate and potassium iodite into the beaker and we put the mixture into the funnel and we recorded it and the mixture is turning to a clear.
